7.5/10

The manga is good, i like the Kaiju idea, feel fresh compare to a lot of isekai nowaday. I enjoy reading it. The only downside is that they end it too quickly, i don't know if it got axed or not but the final arc is really not that satisfy. Reno and other members didn't even have any screen time to show of there training. They have a lot of plot potential like worldwide Kaiju and the mystery on how Kaiju 8 identity and such. Still fun too read

Untitled review

So I have slready resd similar stories, I am not saying that it is every third manga with such setting, just saying that it isn't very unique. Passing is good until the last fight, they also could expens more on after telling but I am no writer so you decide for yourself. Also it feels like a part of story and not that significant part.

Meh

It's quite good at the beginning, had a lot of potential, then they just had to make it what it is now, the classic predictable shounen trope.. u could still read it tho as it's not bad.

Bad pacing and bland story telling

This is a comic I gave up and then finished, the story doesn’t leave much to be desired and the final fight pacing is really awful and goes too long, it feels like half the the story is the last fight, and it’s something you’ve seen before. If you li...
